Watch Review

As you’d expect from a G-Shock watch we have this really bold oversized design that really stands out on your wrist. The watch has a dual analogue/digital display that a lot of people are really fond of. This is another highly functional G-Shock watch that has that typical high level of durability.

The dial design is quite interesting on this model, we have these hands with this slightly hollow effect mixed in with two separate digital displays, this allows you to view a huge amount of information at the same time.

There’s a mineral style crystal glass protecting the dial of the watch. Mineral glass is specially hardened to offer a good level of scratch resistant. It’s ideal for shatter resistance as well, which is a key thing G-Shock wanted to focus on.

Casio’s G-Shock range are known for their military-esque style with these bold oversized designs. Built to offer a high level of shock resistance, the stainless steel casing is covered in this thick protective resin that gives you this extra tough finish.

Taking a closer look at the size specifications of the watch now. The casing diameter is an impressive 52mm which makes this a pretty huge watch. The thickness is 19mm that makes it a very thick timepiece. A lot of people really love these thick oversized designs of G-Shock watches, however, people with smaller wrists may not find them that suitable.

The watch is full of useful functions, it has a stopwatch, countdown timer, day & date display, multi-time zone, backlight, and an alarm. As you can see many of these can come in quite handy, it’s worth noting that people have stated the backlight isn’t brilliant, however.

At the heart of the watch, we have a Japanese made quartz movement. These are affordable, reliable, and accurate. Perfect for an affordable quality timepiece.

To go with the rest of this oversized design we have a fairly wide 26mm resin strap. The watch fastens with a sturdy double prong buckle clasp.

To top the watch off it has a fantastic 200m water resistance rating. This makes the watch suitable for professional marine activity, serious surface water sports and skin diving.

My Final Thoughts On This G-Shock GA-400-1BER Review:

The G-Shock GA-400-1BER is another G-Shock watch that’s suited for those with their active outdoor lifestyles or a keen interest in extreme sports. The G-Shock range continues to remain one of Casio’s best-selling collections, and for very good reason, they offer a high-quality durable watch at an affordable price. Overall this is another brilliant watch from G-Shock.

After looking into the watch design, quality, features, and pricing this watch received an 8.5/10 from us at The Watch Blog.
